A particular; feature of my invention; lies inaan arrangement whereby the spools are somounted that,the threadmaykbe withdrawn longitudinally.

As a result, ,,while :the [spools are -.mounted L in freely rotatable :manner, the withdrawal. ofthread does.not induceunnecessary and-undesirable=ro- 1 tationoftheEspoolsr,

. a In a preferred embodiment,- the. spools are arranged with their; axes. substantially vertical; means being provided for withdrawing theithread inia'sub'stantially upward: direction.

Briefly, my invention resides in'the provision of a supporting panel with a spool rotatably j mounted on its obverse side; the'provision of an abutment spaced from the panel and aligned with thespool for preventing withdrawal of the spool from the panel; and the provision Olen-- 'closable means on the reverse side of the panel for securing the abutment against movement away from the panel. Preferably, the spool is mounted upon a pin Which extends through the panel, the abutment being arranged on the pin,

itself, and the rear end of the pin being" releasably engaged by a nut which may be enclosed to bar unauthorized access to it. 1

I achieve the foregoing objects, and such other structe in accordance ,with the o heij r-e ier ingw h lock the panel I0 to the enclosure.

' In accordancewith invention a panel l0 29 srm ide -iwi hia e es of uitabl sp p ingszwithin which pins-ll are .mounted Each pin has an attenuated end{-- portion, preferably exteriorl tthreaded which extends through the panelulllgsol that it; maybe releasably engaged g5 by athumbnut l z-orthe like on the reverse side o zt epane z-i h At itsouter end, each pin-is provided withthe argern abutment l3;

...E ach pin stof ;sucl1;}asizel that it may convena0 jremovably associated with this box-like enclosure,

and I have illustratively shown'a hinge at one side of the device anda loop-and-hasp arrangement 2| at the opposite side of the device. A padlock-22, or similar locking means, serves to In use,-a suitably authorized person removes the lock 22 and elevates the panel ID so as tomake its reverse side accessible. Any, desired one or more of the thumb nuts I2 is then released, whereupon the corresponding pin l I may be withdrawn outwardly. The desired spool of thread is then slid over the pin II, and the latter is replaced into association with the panel Ill, the thumb nut I2 being then reapplied. This firmly secures the pin H to the panel [0 and secures the abutment l3 against movement away from the panel. Nevertheless, the spool is loosely mounted on the pin so that it may freely rotate, if necessary; and the spool is readily accessible for withdrawing thread from it in a substantially longitudinal direction. After (all the desired spools of thread are mounted in association with the panel ID, the later is then secured to the enclosure beneath it; and the lock 22 or other locking means is then reapplied so as to bar unauthorized access to the nuts l2.

As a result of this arrangement, an operator in need of additional thread must necessarilyapply to an authorized party to manipulate the present spool carrier in order to gain access to'the,

reverse side of the panel and thereby permit ,removal of an empty spool andreplaceinentby another. In this way, an'accurate check may be retained over the amount of thread that is used. In the illustrated embodiment, the panel ID has been shown octagonal in shape, and the boxlike enclosure beneath: it is' of corresponding shape. It will be understood, however, that the device need not necessarily embody this particular configuration. It will'also be hnderstood that the device may rest loosely on amachine or pedestaliorthe bottom wall l8 may be" rigidly secured either upon a supporting pedestal or in any other desired manner. f

The enclosure beneath the panel and the: panel, itself, may be conveniently made of wood or any other suitable material. The'pins H are-pref erably metallic.' The guidef'hooksl'l may be formed at the extremities of radiating a'r'ms' secured in adjustable manner upon a central post 23 mountedon'thepanel I0.- I V v I draw particular attention to the fact that the present arrangement leaves 'the"spools in readily accessible position, so that the withdrawal of thread is a relatively simple matter which does not interfere with nor'impair the smooth con: tinuity of the work which the operator is engaged in. Furthermore, the withdrawal of the thread in a freely upward direction usually'involves little or no rotation of the individual spools, and in this way there is little likelihood of any'excessive pull upon the spools which; might engender the snarling of excess,thread.

In general, it will be understod that changes in the details, herein. described,ahdillustrated for the purpose of explaining the nature of my invention, may be made by "thosesl;illed in,the

art without departing from thespiritand scope of the invention asexpressed in theappended claims. It is, therefore, intended; that these dethe panel, .an abutment spaced from the panel and aligned with the spool for preventing withdrawal of the spool from the panel, releasable means on the reverse side of the panel for securing said abutment against movement away from the panel, and a removable box-like enclosure for said releasable means, said enclosure having means for locking the same to prevent unauthorized access to the interior thereof.

2. In a spool carrier, the elements set forth in "claim 1, said enclosure comprising a box-like member separably associated with said panel on the reverseside of the latter. Y

3. In a spool carrier, the elements set forth in claim 1, said enclosure comprising a box-like member'hinged to said panel to permit relative pivotal movement of the enclosure and panel.

4. In a spool carrier, the elements set forth in claim 1, said enclosure comprising a box-like member having a bottomwall serving as a sup port for the spool carrier, and upstanding side walls, the panel conforming in shape tothat of said bottomwall so as to serve as a cover for the box-like member.

5. In a spool carrier, a supporting'panel, a pin extending through said panel, a spool rotatably mounted on'said pin on the obverse side of the panel, an abutment on the pin for preventing outward withdrawal of the spool from the pin, releasable means on the reverse side of the panel for engaging the pin to secure it against outward withdrawal from the panel, and a removable'boxlike enclosure for said releasable means, said enclosure having means for locking the same to prevent unauthorized access to the interior thereof.

6. In a spool carrier, the elements set forth in claim 5, said pin having a threaded end, and said releasable means comprising a nut engageable with said threaded end.

'7. A spoolcarrier comprising a box-like enclosure having means for locking the same to prevent unauthorized access thereto, a spool supporting pin at the obverse side of said enclosure and having anend portion removably'projecting through a wall thereof, the opposite end portion of said pin having an abutment for preventing outward withdrawal of a spool from said pin, and releasable means within the enclosure for engaging theinner end portion of the pin to secure it against outward withdrawal from the enclosure.
